Application filed November 12, 1921. Serial No. 514,497.

To all whomzzf may concern:

Be it known that I, EDWIN F. BEUGLER, a citizen ofthe United States,residing at Buffalo, in the county of Erie and State ofNew York, haveinvented new yanduseful Im* provements in Machines for Rounding andSizing `Barrel Heads,iof which the following is a specification.

This invention relates to` a machine for rounding and sizing barrelheads and the like. f. 'i

` The principal object of the inventionis to provide a reliable and.efficient machine of this character which is adapted to round and shapenew heads from squarestock as well as resize old heads. p. i o

Another object is to provide means for automatically releasing 'theoperating parts of the machine when the work ofrounding the head hasbeen performed or completed on it. i V

A still further object ofthe invention is to provide a machine which issimple and compact in construction, which is capable of turning out amaximum numberof finished heads in a minimum period of time, and whichis easily operated and .not` liable to get out of Order.

In the accompanying drawings: Figure l is a side elevation of themachine, partly in section, showing the parts inl their operativepositions. Figure 2 is a. horizontal section on line 2 2, Fig. l.

Similar characters of reference indicate corresponding views. i f l Theframe for supporting the variousV working parts of the machine maybe ofany suitable construction, but as shown in the drawings, the samepreferably comprisesa base or pedestal 20, an Overhanging armv2lextending from one side thereof, an-d an overhanging substantiallyU-shaped armor goose-neck 22 on the opposite side thereof. 23 `indicatesa horizontal head supporting l plate fixed to the upper end of a freelyrotating upright spindle 24; journaled substantially centrally in thepedestal 2O.k The lower end of this spindle is preferably sup-` portedon a `step-,bearing consisting of an adjusting screw '25 mounted on alug 26 on the rearside of the pedestal and a. ball bearing 27 interposedbetween the headv of said adgusting screwv and a cap 28 secured Ato thelower end of the shaft by apin `29,

as.v shown in Fig.- 8. rllhe upper ,p end of the spindle is'supported inbearings 30, `30

formed in the upper end of the pedestal Vof f the machine, as showninFig. `6. For a pur-l pose which will, hereinafter appear, `said spindle24;H is permitted a slight vertical `movement `in its bearingsrelatively to the cap 23, and to permit suoli movement the ends vof thep1n29 pass through correspond` ing upright slots 31 in said cap andacush-` parts throughout the'several ioning or shock absorbing spring 32is ini i terposed between the opposing ends offthis shaft and its cap.

Movable vertically to-ward and from the head supporting plate 23 is arotatable clamping `plate or disk- 33 providedy near its periphery witha plurality of radially,- spaced spring-pressed clamping pins 34 whoseends are pointed to grip orbite into the barrel headingbeing worked, andthereby hold it firmly and tightlyv on the supporting plate'to enable itto revolve `with the clamping plate. As shown in Figs. 1, 2, and 6,these pins are preferably arranged in pairs, each pair being mounted ina holder 35- adjustable radially on the clamping disk to suit headingsof different diameters. This adjustment may be effected in any wellknown manner; for example, by providing each holder with alongitudinalslot 36 for receiving the shank of an adjusting bolt 37 secured to theclamping plate. The latter is fined to the lower end of a driven spindle3S which is arranged in axial alinement with the spindle 24 of the headsupporting plate and which is capable of reciprocating vertically in itsbearings 39 and 40 to move the clamping plate 33 toward and from saidhead supporting plate.

The means for actuating the driven spindle 38 to move the clamping`plate 33 toward and from the head supporting plate 23 are preferablyconstructed-as follows:

Mounted on the front end of a transverse `rock shaft 4l journalled inthe upper side of the goose neck arm 22 is a verticallyswingingactuating lever 42 having an upper arm 43 and a lower sectional arm 44,45, the former extending inwardly from its fulcrum .and the latterextending downwardly therefrom, as shown in Figs. l and 6. The free endof the arm 43 is bifurcated, as shown at 46, to embrace the spindle 38.These bifurcated portionsV are provided with notches or recesses 47which engage trunnions 48 projecting from the opposite sides of a collar49 loosely mounted on said spindle 38 and held against verticaldisplacement there- 'on by collars 50, 50, arranged on opposite y45,overlap one another in the plane of the lever, and the rupper end of thearm section is pivoted at 55 to a lug 56 depending from the upper end ofthe arm section 44.

- The lower end of the latter is provided with an adjusting screw 57which abuts against the opposing outer side of the arm section 45. Bythus constructing the lever 42, relative adjustment of the arm sections44, 45, .is permitted, whereby the stroke of the arm 43 may be regulatedfor the purpose of exerting more or less pressure of the clamping plate33 on the heading.

rllhe clamping plate and associated parts are held in their elevatedinoperative position, shown by dotted lines in Fig. 1, by means'of acoil spring 58, its lower end being connected to the base ofthe pedestal2() and its -upper end being connected to an adjusting rod 59 which isin' turn connected to the end of a crank arm 6() mounted on the rear endof the rock shaft 41 and extending outwardly therefrom. This springtends constantly to rock the arm 6() downwardly and move the arm` 43upwardly to normally hold the clamping plate above the head suping inposition on said plate. It will be noted, that in this position of theparts, the operating leverv 54 assumes the dotted line position shown inFig. l, its roller 53 engaging the upper side ofthe dwell 52 and thespring 5S tending to hold the lever in such position. To cushion thereturn movement of this operating lever, a buffer spring 61 is providedwhich is mounted on a substantially upright rod 62 fastened at its lowerend to the pedestal base and passing through an elongated opening in theadjacent portion of said lever.

Means are provided for holding or locking the operating lever 54 in itsdepressed or operative position, shown by full lines in Fig. l, withoutnecessitating the operator to retain his foot on said levery to hold itin such position. The preferred means for accomplishing Athis resultcomprise a locking pin 63 carried by the operating lever and a hook 64formed on a verticallyswinging release pedal 65 with which said pin isadapted-'to engage. This pedal is fulcrumed on a transverse shaft 66supported on the pedestal or base and provided-at its rear endl with arock arm 67 which is connected with the pedestal or adjacent fixed partby al coil spring 68 which tends to hold y,said pedal upwardly so thatits hook 64 is .I

constantly in the path of the locking pin 63 of the operating lever. Theupper portion of the hook is provided with an upwardly and outwardlyinclined face 69 against which said locking pin bears before the hooksnaps into locking engagement with its pin.l When it is desired torelease the operating lever to return the parts connected therewith totheir inoperative position, the operator presses downward on the releasepedal 65 to release its hook from engagement withy the locking pin ofsaid operating lever, whereuponthe spring 58 immediately raises thelatter to the position shown by dotted lines in Fig. l.

The cutter mechanism for chanifering or cutting the heading on oppositesides of the peripheral edge thereof is preferably constructed asfollows:

7 0 indicates a cutter supporting carriage or yoke whichis movable orslidable hori- Zontally toward and from the head supporting plate 23 ina plane substantially at right angles to the axis of the latter andwhich is suitably guided for movement on a table 7l formed on the uppersideof the pedestal arm 21. 7 2, 7 3 represent upper and lower cutterheads having cutters 74 projecting from the `peripheries thereof whichare adapted to engage opposite sides of the peripheral edge of the work.These heads are mountedl on parallel shafts 75, 76 journaled in thecarriage and provided with pulleys 77, 78, respectively, around whichpasses a belt 79 connected to a suitable source o-f power.

^ the` cutting operations togloe directed rear` y prevent interferenceAs shown in F il, the upper cutterl head is offset rearwardly above thelower head to of the `cutters, and' the belt 7 9 passes aroundI thelower side of the lower pulley 7 8, then upwardly around the upper sideof the upper pulley 77, and' thence downwardly around the lower side ofa flanged pulley 8Ol mounted on a shaft 81 liournaled on the rear sideof the carriage 70. By this arrangement the cutter head-s are driven inopposite directions `to cause the chips removed from `the heading duringwardly away from the operator.` As shown in Fig. 1, al Space 82 isformed in the carriage between the upper and lower cutter heads forpermitting the ready passage of such chips through it onto theflfo'or.

The cutter supporting carriage is xmoved inwardly into its operativeposition through the medium of the operating lever 54, the movement ofsaid carriage taking effect after the heading has been clamped betweenthe head plate23 and the` clamping plate 33. .In other words,y theinitial-stroke of the operating lever clamps the heading ,and the. finalstroke thereof moves the cutter into Contact with 'the heading. f Foraccom ,plisliing this result, the carriage is adjust-- ably connected toa longitudinally movable shipper rod 83 arranged on the front side ofthemachine and provided at either end with screw threads 84, 85, the.threaded por tion St engaging a correspondingly threaded. opening S6` ina lug 87 depending from the lower rear end of said carriage and thethreaded portion 85 passing freely' thro-ugh an opening 88l formed in ab`oss89 on the front side of the goose neck arm 22 of theframe. Mountedon the threaded port-ion 84 of this rod is a tappetcollarincluding aflanged nut 90 anda similar flanged nut 91 jammed aga-inst i-t withwhich a tappet arm 92, forming an integral part of the olperat- .inglever 54, is adapted to engage for shift-- lng said rod and the cuttercarriage to its operative position, shown by fullv lines in Fig. 1.Fixed on the threaded end 85 of the shipper rod isa hand wheel 93 forroi-- tating the latter to adjust the cutter oar-- riage and interposedbetween the hub of said.-

wheel' and the outer face ofl theA `boss 89I is a cushioning' spring 94.`The cutter'cai riage is moved to its inoperative position, shown bydotted lines in Fig. 1, by means of lan upright lever 95 fulcrume'd on aknife edge 96 formed on the side of the pedestal S20, the lower arm ofthe lever being con--l nected to a spring 97 rexten-ding through thepedestal and att-ached atits opposite',A end toy the eye of an adjustingscrew 98', while the.

upper arm of the lever extends into` an iii-- wa-rdly opening verticalslot or'reeess 99" forn'ied on the inner side of a flanged collar 100loosely mounted on the rod 83. Said -I-n this capacity .the nuts "whichare supported on the "relatively thereto, one of said ears beingconspring 97 ten-ds constantly to rock the upper against the closed endof the recess 99. as

shown in Fig. 10. The outward movement of the cutter carriage is limitedby the hub of thehand wheel 93 coming in contactwith the cushioningspring 94.

The opposing faces of the flanged portions of the nut 90 and the collar1.00 are preferably radially corrugated orknurled as shown at. 101, toprevent turning of said nut relatively to the shipper rod 83 when'thelatter is turned in one direction or the other to effect a correspondingmovement of the cutter carriage 70, said collar being held againstturning by the upper arm of the lever 95 kentering the recess 99therein. During the rotation of the shipper rod to effect an adjustmentof the cutter carriage to suit a barrel head of a certain diameter, saidrod is held against longitudinal move ment in one direction by the`return lever 95 and spring 97 rand in the oppositedirection by the handwheel A93 abutting against the cushioning spring 94C. Upon turning thehand wheel in one 'direction or the other the directiontoward or fromthe nut 91 against which vthe arm 192 ofthe operating lever abuts.`During the turning of the shipper rod, the nuts and 91 turn with it, thecollar yieldingsuiiiciently to permit such turningof these nutsrelatively to said collar; 90 and 91 act similar lto` a ratchet, theinterlocking corrugations making these nuts self-locking and 'ipreventing the rod from turning yduring the normal operation of themachine.`

A suitable gage device is provided for conveniently setting the cuttercarriage. to shape and resize heading to a. `certain diameter. As shownin Figs. v1, 8 and 11, this gage device preferably coi'i'iprises a fixedindicator or pointer 102 overhanging the upper front side' of thepedestal lOfaiid a gage 'plate 103 movable longitudinally relativi-ily'to said indica-torl and provided valongits upper edge with graduations10-1 corresponding to the diameters of barrel heading within a certainrange. `This plate is provided on its rear side with guide ears 105y rod83 to move nected with the front end ofthe cutter car- V'riagefbya rigidlink 106, 'so that when the carriage is moved in one direction or theother, the gage plate is moved in a corresponding direction.

AThe `means for driving the rotary spindle 338 of the. clamping plate33and connecting y'and disconnecting the same from the source of`powerare lpreferably constructed as follows: v l

, The outer end a tappet finger 126 107 represents a horizontaldrivingshaft arranged lengthwise atthe upper end of the machine and journaledin a bearing bracket 108 suitably secured to an extension 109 of the arm22 of the frame. Loosely mounted at one end of this shaft is a ,conepulley 110 adapted to be connected by a belt 111 with a source ofpower,while its other end is provided with a worm gear 112 which mesheswith a worm wheel 113 vmounted on the upper end of the spindle 38.y Thelatter is compelled to turn with its worm wheel but is capable ofsliding vertically through the hub thereof by means of a spline 114. Theworm wheel is held against vertical displacement at its upper end by ahousing 115 and at its lower end by the upper face of the bearing 40, asshown in Fig. 6. The pulley 110 is held against longitudinal movement onthe shaft 107 by its hub abutting at one end against the outer end ofthe bearing bracket 108 and at its other end against a collar 116 pinnedto said shaft. of the pulley terminates in a jaw clutch member 117 withwhich a movable jaw clutch member 118 is adapted to engage. This movableclutch member is slidable on the end of the shaft but is compelled toturn therewith, and for this purpose said shaft is provided with atransverse pin 119 whose ends engage longitudinal slots 120 formed inopposite sides of a sleeve 121 formed integrally with said movableclutch member. The meansl for controlling the latter are preferablyoperatively connected with the shipper rod 83 to engage the clutchsimultaneously with the movement of bringing the cutter carriage 70 intoits operative position. To this end a substantially uprightvertically-swinging actuating lever 122 is provided which is fulcrumedintermediate its ends on the rear side of the gooseneck arm 22, as shownat 123, the upper arm being provided with a fork 124 which engages aperipheral groove 125 formed in the outer end of the movable clutchsleeve 121. The lower arm of this lever is offset forwardly and upwardlyaround the lower side of the arm 22 to form on the front side of themachine between said arm and the rod 83. Adjustably mounted on theAthreaded portion 85 of the latter is a tappet collar 127 having a flange128 which is arranged in the path of the tappet linger 126. This collarmay be held in a set position by a lock nut 129. By this arrangement,when the operating lever 54 is depressed to first lower the clampingplate 33 and secondly, to shift the cutter carriage inwardly so that itscutters contact with the heading to be shaped, the flange of the collar127 simultaneously with the second-named movement contacts with thetappet 126 of the lever 122, and rocks it from the dotted line positionshown in Fig.

'weight 139 for 6, to the full line position shown in the saine figure,yin which position the clutch is engaged and motion is transmitted tothe spindle 38 to rotate the heading pastthe cutters. n

A spring 130 may be interposed between the end of the shaft 107 and theclosed end of the movable clutch member to insure a prompt disengagementof said memberwhen the operating lever is released to return the severalparts to their inoperative positions.

MeansV are provided for automatically releasing the operating lever 54from its depressed or operative position, as soon as the work of shapingthe barrel headhas been performed, and thereby disengage the clutch 117,118, shift the cutter carriage 70 away from the work, and lastly,elevate the clamping plate 33 to enable the finished head to be removedfrom the supporting table 23. To properly finish a barrel head, the samemust revolve atleast a revolution and a fraction thereof past thecutters. The means for thus releasing the operating lever are controlledby thexrotation ofthe heading and as shown in Figs. 3, 8 and 9, arepreferably constructed as follows: n

131 indicates a windlassing spool which is loosely mounted on thehead-plate spindle 24 below the lower bearing 30 and which is confinedbetween two friction disks 132, 133, the lower one being formed on thecap 28 of said spindle and the upper one being formed on a collar 134secured to` said spindle. Fastenedto this spool is one end of a cable orchain 135 which passes horizontally and outwardly through an -opening136 in the pedestal 20, then around the upper side of a' pulley 137mounted on said pedestal and thence downwardly where its lower end isconnected to an arm 138 formed integral with the rock arm 67 which isyieldingly connected with the pedestal by the spring 68 for normallyholding the hook 64 in engagement with the locking pin 63 of theoperating lever. The cable is provided below the pulley 137 witlracounterbalancing normally pulling the cable downward to unwind it fromthe spool. As previously described, the spindle 24 is capable of aslight vertical movement, this being for the purpose of permitting theupper 'disk' 133 to frictionally engage the spool 131 when the clampingplate is brought down to clamp the heading to the supporting plate 23,and thereby enable thefcable.

to be wound up on the spool and at a predetermined point cause theoperating lever to be released from itshook v64. Then the `cable iscompletely unwound from the latter, as shown by dotted `lines in Fig. 3,there is sufficient slack provided to allow the head clamping device torevolve, say, one and a quarter revolutions, at which time the cablebecomes taut and continuing to wind up on the spool, raises the arm 138which rocks the `shaft 6G and releases the hookl from engagement withthe locking pin in the operating-lever, whereupon the latter is elevatedto its inoperative position. As-

tion disk 133 from engagement with the op posing tace of the spool 131,whereupon the counterweight 139 is free to drop by gravity and unwindthe cable from the spool.

llVhen reshaping or resizing round barre-l heads, means are provided forcentering them on t'he head supporting plate 23. As shown in Figs. 1, 2and 6, the centering device preferably comprises a series of verticallydisposed centering arms 140 mounted on supporting sleeves 141 guided formovement on radial rods 142 securely fastened .at their inner ends inbosses 143 formed in a supporting ring orhub 144 held in a lined posi-ytionen the upper bearing 30 of the spindle 24. Mounted on this ring toturn thereon is a collar 145 having a series of radial lugs 146 andpivotally connecting the latter with the sleeves are links 147. 148indica-tes an ooeratino' rod extending forwardl trom said collar bymeans `of which'the latter is turned in Vone direction or the otherto'eliect a corresponding inward or outward move- -ment vof thecenteringsarins 140. The latter are preferably rulcru-med on saidsupport-- ing sleeves, as shown in Fig. 1, and their lower ends areconnected withV the sleeves" by springs 149, which maintain them in anormally inclined `position with their upper ends projecting above theyheading, While they are permitted to yield downwardly be* low the planeof the heading should they encounter some obstructionon the heading asit is being turned and shaped.

Briefly, the operation of the machine is as `follows:

The heading, Whether square stock or round heading which is to beresized is placed on the supporting plate 23 and properly centeredthereon. The operator then p depresses the operating lever 54, .theinitial movement thereof forcing the clamping plateI 33 onto the headingto ,reliably clamp it to the supporting plate, and then the Afinalstroke thereof simultaneously bringing the cutters finto contact Withthe heading and throwing in the clutch 1171, 118 to rotate the spindle38 to impart rotary motion to the `heading relatively to theI cutters.After the heading revolvesa revolution and a quarter past the cutters,the cable 135 is drawn 4taut and .auses the hool; 64 to be released fromthe locliing pin 63, allowing the spring 58 to return the operatinglever to its inoperativeposition, shown by dotted `lines in 1, whichmovement results in the clutch be,- ing disengaged, the cutter Ycarriage being moved away from the heading, and the clamping plate'33being' elevated above the heading, as previously described. The linishedhead is then removed and the operation repeated. Y v Should the operatorWish to stop the maw chnebefore the vWork on 'the heading is completed,he simply depressesy the pedal 65 ywith his foot to release the`operating lever. lfrom the hook 64, Which Will immediately canse themachine to come torest.

It desired, the clamping plate 33 may be rotated by hand instead of bypower. An arrangement suitablel for this purpose is shown in Fig. 15,Whereinthe povver` driving mechanism previously described, is removed,and substituted therefor is a hand Wheel 150 secured to the upper end ofthe spindle 38 and provided with ar circular ratchet bar 151.Cofoperating With this bar `is a pawl 152 pivoted to the extension 109ing member movable toward and from said supporting member, a cuttermechanism guided on said frame andniovable toward and ftroin `theperipheral edge of the Work on a line perpendicular to the axis of saidsupporting and clamping members, and an operating lever fulcrumed onsaid frame and operatively connected to said Clamping member andsaidcutter mechanism to successively move said parts to their operativepositions.` P v 2.
